Fig.4 is a detail in-section on the 1me4 4- Fig. 5 is a fragmentary vertical section taken approximately on the line 5-5 of Fig. 1; p

, Fig. 6 is a fragmentary section taken on the line 6- -6 of Fig. 3;

Fig. 7 'is a section on the line 7--7 of Fig. 3.; and Y Fig. 8-is a bottom plan view of the board, showing the legs and brace'members folded against the top or board proper.

The ironing boar'dhas the. customary top board .or board proper indicated by the numeral 8. To the under side of the rear end of thisboard 8 is riveted, bolted or other wise rigidly secured, a hinge bracket 9 which, preferably, is-in the form of a strapwhich, as shown, is a cast structure and is provided near its ends withdepending downwardly diverging hinge lugs 10 arranged in pairs with the pairs of lugs-parallel and tiedte ther at their outer edges by integrally firmed back webs 10.

The rear legs 11 work betweencthe pairs of hinge lugs 10,-are pivoted theretoat 12-, and when turned downward into operative up- Y right positions, they will .be forced against, the '45 the. backward ,movement thereof, as best webs 10, which latter act as stops, limiting shown in Fig. 7. In'view of-the fact that the two pairs of hin e lugs 10 diverge downwardly,:it' follows, 0 course, that when the rear legs. 11 are turned downward, they will di- Fig. 3 is a transverse vertical section taken verge and s read toward their lower floorengaging on s, but'inasmuch as the two pairs of lugs v further follows that the legs 11, when turned against the bottom of the board 8, will be parallel. Otherwise stated, in view of the .divergence of the hingelugs, ,the legs 11 will be caused to spread at their lower ends a dis- 10 in horizontal section are parallel, it

tance wider than the board, and when turned upward against the board, will be spaced-less than the width of the board. This spreading of the legs, of course, is important because it gives greater stability to the board'when in use and brings the legs within the width of the board when out of use.

i The third supporting'leg'13 is an oblique leg pivotally connected to the bottom of the board, preferably forward of the bin e lugs] 10 and, as shown, directly connecte by a pivot belt or rivet 13 to hinge lugs 14 secured on the bottom of the'board. The'upper end of the oblique leg 13 is extended rearward of its ivot and, as shown and preferably, is provi ed with a rubber abutment .13 that is ada ted to be pressed against the bottom of the oard 8, This abutment 13 is desirable because it increases the resilience in the leg 13 and com ensatesfor'variations in the adjustments 0 the several'parts.

vTop brace bars 15 are pivotally connected to the lower portions of the legs 11 and, at their free ends, are detachably engageable with a lock strip or stop 16 on the bottom of the board 8. The converging-free ends of the brace bars 15 are tied together by a short cross strap 17. A bottom brace 18 connects the lower end of the oblique leg 15 to lower portions of the rear legs 11.

Preferably and as shown, this bottom brace oted-heads 2Q, but, attheir rear ,ends, are

b a staple 19. or thetl i's bottom brace 18' brace, the arms of which are rigidly secured to said rear legs and the upper portion of which is formed with a camsurface engageable with said bearing member and operative to depress and spread said brace when said legs are turned downward, and an abutment on the bottom of said board, adjacent said bearing member, operative to prevent said brace from being forced beyond the planes of said legs when the latter are turned downward and said brace is depressed and spread. In testimony whereof I aflix my signature.
